Claw jaws
Description The SCHUNK claw jaw product range stands for maximum flexibility from the standard modular system - at a reasonable price and with variable applications. Whereas other suppliers can only achieve large clamping ranges by using costly special solutions or with several chuck jaws, SCHUNK offers a maximum clamping range with just one claw jaw. Field of application For all common manufacturers and types of lathe chucks Advantages – Your benefits Optimized clamping contour for maximum clamping force of the whole clamping range Transmission of high RPMs for economic cutting at high cutting speeds High speeds at a low centrifugal force resulting in higher clamping forces due to a low weight Highly versatile clamping ranges leads to significantly lower investment costs Form-fit clamping of the workpiece at a high machining performance and optimum clamping force Additional third row of teeth (from chuck diameter 200 mm) allows for higher cutting data (feed rate, rate of cut, etc.) during "on-the-fly machining" Highest flexibility through standardization Combination options for base, intermediate and top jaws expand the field of application of the standard component range by up to 50%. Extensive product range for I.D., O.D. and bar clamping Case-hardened less wear at the teeth
